Extract

Larvae of the sawfly genus Gilpinia Benson, a Palaearctic genus, attack conifers. Smith (1974) listed 24 species, two of which, G. frutetorum (Fabricius) and G. hercyniae (Hartig), were accidentally introduced into North America. Keys to known species of Gilpinia have been published for adults (Enslin 1917; Takeuchi 1940; Gussakovskij 1947; Berland 1947; Benson 1951; Okutani 1958) and for most European larvae (Lorenz and Kraus 1957; Běnes and Kristek 1979).
